Disposable respirators



March 15, 1960 A. P. JAROSLAW DISPOSABLE RESPIRATORS Filed April 24,1957 IN V EN TOR. JIFKE D I? JAROSLA V M United States Patent DISPGSABLERESPIRATORS Alfred P; Jaroslaw, Mount Clemens, Mich.

Application April 24, 1957, Serial No. 654,7 84 '3 Claims. 01. 128-147)The invention pertains to a respirator or air filter consisting of apliable, small-meshed screen which may be applied over the mouth of aperson and retained in place by a strip of pliable fabric which framesthe screen and is provided on one side with an adhesive substance.

The object of the invention is to provide a respirator capable ofintercepting dust particles carried by atmospheric air, the respiratorincluding a filtering element adapted to be held in a spaced relation tothe mouth, to the front thereof, permitting free movement of the personslips.

Another object of the invention is to provide a respirator capable ofbeing produced at a reasonable cost so that individual respirators maybe discarded even after having been used but once.

Finally, the object of the invention is to produce a respirator of sucha shape that a plurality of them may be packed in a nested relation toeach other so as to occupy but a limited space.

I shall now describemy respirator with reference to the accompanyingdrawings in which:

Fig. 1 is a perspective view of the respirator as applied over the mouthof a person;

Fig. 2 is a front elevational view of said respirator;

Fig. 3 is a sectional view of the respirator on line 3-3 of Fig. 2;

Fig. 4 is a rear elevational view of the respirator with elements partlypeeled ofi therefrom;

Figure 5 is a rear elevational view of a modified respirator with anelement shown in a partly peeled off position.

Similar numerals refer to similar parts throughout the several views. 7

The respirator generally identified by numeral 10, consists of asubstantially rectangular strip, or piece 11, of textile material,having an open central portion 12. The piece has the form of asubstantially rectangular frame in which the upper and lower portions,disposed horizontally, are marked 13 and 13A, respectively. The endportions, disposed vertically, are marked 14, said end portions beingconsiderably wider than said horizontal portions. Secured to saidhorizontal and to said vertical portions and extending over theopenportion 12, is a screen 15 which may be made of such material as gauzeor similar textile fabric, in which the Woof and warp threads are sospaced as to provide a multiplicity of openings. The openings are to besmall enough to intercept particles of dust carried by atmospheric air.The midportion of the screen is shaped into a substantially rectangularcup which occupies said open-portion 12, in the strip 11, while themarginal portions of the screen are secured to the strip by means of asuitable cementitious substance as best shown in Fig. 4.

It will be noted that the screen is shorter than the 2,928,388 PatentedMar. 15, 1960 ice strip 11, so that a free area is left at each side ofthe opening 12, which area is not covered by the respective marginalportion of the screen. Each of these areas is covered by a non-dryingadhesive substance which is indicated in the drawings by a multiplicityof closely spaced dots. These free areas are normally covered by a thinpliable cover which may be made of gauze, paper or some other suitablesubstance capable of being easily peeled off in order to expose saidadhesive substance.

Upon removal of the cover, the respirator may be applied over the mouthof a person, in such a manner that the cup-shaped portion of the screenwill be located opposite the mouth of the person but extending outwardlytherefrom while the end portions 13 will adhere to the face of saidperson about each corner of the mouth and to the adjoining areas of thecheeks. This is shown in Fig. l.

A modified respirator is shown in Fig. 5 in which each of the endportions 18 of the strip 11 is covered by a separate narrow band 20,which may be made of paper or some other suitable material adapted tocover the adhesive coating on the surface therebeneath. Each of thebands includes a corner tab 21, which extends beyond the marginalportion of the strip 11, for easy manual grasp preliminary to thepeeling of the bandfrom the strip.

It will be understood that some other changes may be made in thestructure of the respirator without departing beyond the inventiveconcept disclosed herein.

What I therefore wish to claim is as follows:

1. A respirator for application over and about the mouth of a personconsisting of a pliable sheet member having an open mid-portion and ascreen bonded to one side of said sheet member and including acup-shaped concave convex portion extending beyond the surface of theopposite side of said sheet member, the sheet member having areas coatedwith an adhesive substance for application of the respirator to theareas about the mouth of a person. I

2. A respirator consisting of a pliable sheet member. of textilematerial, the member having an open mid-portion and a pliable screenbonded along its edges to the.

sheet member about the rim of the open mid-portion, said screenincluding a cup-shaped concave convex body fitting into said openmid-portion of the sheet member, the cup-shaped body being of a size toextend over the mouth of a person in a spaced relation to said mouth,

the sheet member having, on one side, areas coated with an adhesivesubstance for adhesion to the face of the person, and pliable sheetmeans normally covering said adhesive substance but being adapted to bepeeled therefrom. V a

3. A disposable respirator adapted to be placed over the mouth ,of aperson, a respirator including a cup-.

shaped screen of a size corresponding to the mouth of a person, and apliable sheet member framing said screen and secured thereto, the memberbeing coated on one side with an adhesive substance as a means to holdthe respirator in place on the face of the person and to hold the screenin a spaced relation to the mouth, forwardly therefrom.
